We treat cooking like a religion and recipes like scripture. But we can’t turn to any hotel nightstand to pull out our bible, so what happens to those recipes when we’re traveling around the world or just moseying to the kitchen? Yum 4 stores and organizes recipes on your Mac, even copying them to a free, companion iOS app. That means you can easily reference a MacBook or iPhone to make impromptu wasabi-and-edamame mashed potatoes while at a cousin’s for the holidays.

The problem: you need to modify the names of a bazillion files. The bigger problem: it’s 2011, but the Finder is still built to edit just one filename at a time. Sure, you could fiddle with the Terminal to do the job, but better yet, you can use Renamer and stick with the OS X you know and love.
